The 2021 Infiniti QX80 is a full-size, body-on-frame luxury SUV with three-row seating, strong towing capability, and a comfortable ride aimed at families who want space and prestige. It competes with rivals like the Lexus LX, Cadillac Escalade, and Lincoln Navigator, leaning more toward durability and highway comfort than sporty handling. This model is part of the second-generation QX80 (introduced for 2014 and heavily updated for 2018), so 2021 benefits from a mature platform and proven powertrain. It’s ideal for buyers who prioritize a quiet cabin, easy power, and long-distance comfort, and who don’t mind higher fuel costs typical of large V8 SUVs.

1) 5.6L V8 power: The 2021 QX80 uses Infiniti’s 5.6-liter V8 (400 horsepower, 413 lb-ft of torque) paired with a 7-speed automatic transmission. Acceleration is strong for its size, and the V8 is a key reason many shoppers choose it over turbocharged alternatives. 2) Rear-wheel drive or 4WD: Buyers can choose RWD for simpler ownership or available 4WD for added traction in snow, rain, and light off-road use. The 4WD system is geared toward stability and confidence rather than rock crawling. 3) Three-row capacity and cargo: With seating for up to eight (depending on configuration), the QX80 is built for big families and frequent road trips. The cabin is spacious, with a high seating position and easy highway manners. 4) Towing capability: Properly equipped, the QX80 is rated to tow up to about 8,500 lbs, making it a solid choice for boats, trailers, and campers. The V8’s torque and body-on-frame construction suit towing better than many crossovers. 5) Driver assistance and luxury touches: Many 2021 QX80 models include features such as adaptive cruise control, blind spot warning/intervention, a 360-degree Around View Monitor camera system, heated/ventilated front seats (trim dependent), and a premium Bose audio system.

Shoppers researching 2021 Infiniti QX80 reliability and 2021 Infiniti QX80 common issues will find that the core drivetrain is generally durable, but a few patterns show up in owner complaints and service discussions. 1) Infotainment and connectivity glitches: Some owners report Bluetooth pairing issues, system lag/freezing, or navigation/audio quirks. These can appear at low mileage and are often resolved with software updates, resets, or module servicing. 2) Brake wear and vibration: The QX80 is heavy, and some owners notice brake pad/rotor wear sooner than expected or feel steering wheel shake under braking (often due to rotor warping or uneven pad deposits). Symptoms can appear anywhere from roughly 20,000–50,000 miles depending on driving style, towing, and terrain. 3) Suspension/steering noises: Clunks or rattles over bumps can develop as miles add up, sometimes related to sway bar links/bushings or other front-end wear items. On a vehicle this size, worn components may show up around the 40,000–80,000-mile range, especially on rough roads. 4) Parking sensor/camera warnings: Intermittent parking sensor alerts or camera-related warnings are occasionally reported, sometimes tied to sensor contamination, wiring issues, or calibration problems. It’s usually more annoying than dangerous, but it’s worth diagnosing properly.
